L. G. PACENT INDUCTANCE COIL MOUNTING Filed y 24, 9 2 Sheets-Sheet 2 [00/5 6. H4CE/VT auoento'a abliozue asioeso shaft 16 is coupled to the hollow shaft 26 through bevel gears 27. Shaft 16 and the coil carried thereby may be rotated by turning the knob 28. Pin 24- corresponds with pin 24 of Fig. 3 and is threaded into the hollow shaft 24. By holding knob 28 against rotation, the operator may turn knob 25 so as to move the end of pin 2t" toward or away from spindle 23" thereby clamping or unclainping the coils with re spect to horizontal adjustments.

The two adjustments of the movable coils give a. Very much wider range of coupling than can be obtained with a single adjustment in a unit structure of moderate size. as will be quite obvious to those skilled in theradio art.

ll claim:

1. An adjustable inductance coil mount ing comprising a bearing member, a spindle about which said bearing member is rotatable, a pair of angularly disposed shafts journaled in said bearing, pair of gears inter-connecting said shafts, and means carried by one of said shafts for supportin an inductance coil, said last-mentioned shaft having an axis of rotation disposed at an angle to the axis of rotation of said spindle 2, An adjustable inductance coil rnount= ing comprising a bearing member, shaftjournaled in said bearing member, a coil su porting member carried by said shaft, a liollow shaft journaled in said bearing member and disposed at an angle to said first shaft, a pair of gears interconnecting said shafts, a spindle having an axis of rotation at an angle to both of said shafts, said bearing member being" adapted to rotate about said spindle, and a set screw extending through said hollow shaft, the end of said set screw being adapted to engage said spindle, said set screw being threaded into said hollow shaft.

in testimony whereof ll affix my signature,
